Threema app for iPhone and iPad
Threema is the world’s favorite secure messenger and keeps your data out of the hands of hackers, corporations and governments. Threema can be used completely anonymously, allows to make end-to-end encrypted voice calls, and offers every feature one would expect from a state-of-the-art instant messenger.
PRIVACY AND ANONYMITY
Threema is designed to generate as little data on servers as possible – this is a core part of our concept. Group memberships and contact lists are managed on your device only, and never stored on our servers. Messages are immediately deleted after they have been delivered. Local files are stored encrypted on your mobile phone or tablet. All this effectively prevents the collection and misuse of your personal information, including meta data. Threema is fully compliant with the European privacy legislation (GDPR).
HIGHEST ENCRYPTION STRENGTH
Threema encrypts ALL your communications END-TO-END including messages, voice calls, group chats, media files and even status messages. You can rest assured that only the intended recipient can read your chats, and nobody else – not even us. Threema uses the trusted open source NaCl cryptography library for encryption. The encryption keys are generated and safely stored on user’s devices to prevent backdoor access or copies.
Threema is not only an encrypted and private messenger but also versatile and feature-rich.
• write text and send voice messages
• make voice calls (requires iPhone 5s / iOS 9 or above)
• share videos, pictures and locations
• send any type of file (pdf, animated gif, mp3, doc, zip, etc.)
• create groups
• conduct polls with the unique poll feature
• choose between a dark and a light theme
• quickly and silently reply with the unique agree/disagree feature
• verify the identity of a contact by scanning their personal QR code
• use Threema as anonymous instant messaging tool
• synchronize your contacts (optional)
Each Threema user receives a random Threema ID for identification. A phone number or email address is not required to use Threema. This unique feature allows you to use Threema completely anonymously – no need to give up private information or to open an account.
We let users confirm trusted contacts with a QR code or a key fingerprint to prevent man in the middle attacks.
We are a 100% independent and self-financed company in the heart of Switzerland with its own servers and in-house software development. Switzerland is a country with some of the most user friendly privacy laws in the world.

Pros and cons of Threema app for iPhone and iPad
Threema app good for
[EDIT] Notification alert sound bug disappeared with no reason.
Anyhow, theres still that annoying location bug for as long as I can remember. When someone shares their location, the map is unstable. It is initially centered on the other partys location (green dot) as this is the intended purpose, but soon after it quickly moves to *our* location (blue dot), and we can no longer see the other persons location unless fiddling with the little icons on bottom part of the screen.
Threema! Great app! Worth every penny.
No glitches. Runs as smooth as iMessage but better since its fully secure. Youll never have to worry about your information and messages being intercepted with
Threema for about 5-months now. It definitely needs GIF support, but other than its an awesome way to send and receive encrypted messages free from prying eyes.
Ive been using
Threema so much that I use it as my primary messaging app. Unfortunately, not everyone has it yet. A suggestion might be to implement an interface we can receive and respond to non Threema text messages (similar to Facebook messengers recent update where we can respond to text messages from within the app!) that way we would not have to continue to switch between apps for conversations but i understand that that might compromise the security of the corporation because thats what Threema is known for.
Ill forever recommend this app to everyone looking for a secure messaging portal and I continue to look forward to your updates
The app works fine and has many pros. Its not tied to a phone number which is nice. Though Im unsure how much I can trust the app Im sure it is good enough for general texting and photo sharing.
1) Pin to open the app (optional)
2) Read receipt
3) Very customizable
4) you can see when someone is responding.
5) Group messaging
1) No audio calling (VoIP)
2) Open up the code for security audits by everyone
Until number two happens, have Signal on your phone for calls and more private conversations.
Good app and seem like good devs behind it, but refusal to allow open source inspection of code makes me a little less comfortable.
A competitor Signal is open source and researchers found a bug and it was quickly patched. All software has bugs and its sometimes hard for a dev team to catch all their own bugs.
For all the very low ratings, understand this is not intended to compete with whatsapp or messenger. This is a serious app with a niche market and focus. The nature of it makes it inherently less convenient than those other mainstream apps.
Some bad moments
I didnt put in my email or any other self identifying information. Im trying to send to someone elses ID who did the same. It appears you cannot do this. Am I wrong? If not please fix this. My situation is even more secure without self identifying information. Without this scenario I dont see that this app is necessarily more secure than other apps. As part of my profession I do computer security as well
Update: I tried to add my contact by the text ID and it keeps saying request timed out. It also times out trying to verify the photo of the ID using my iphone on iOS 10. My friends ipad worked when adding me as a contact however. Then I sent a msg to my phone and it never showed up after a day now. App seems to have a few issues. Im very disappointed out of the gate
App not connecting to internet on an iPhone 6S, running iOS 10.2, using T-Mobile.
